Description

Description: FIELD OF USE The present invention relates to a cargo handling device for a ship for carrying packed goods, in particular a cargo pallet carrying the goods, the cargo handling device being provided at each free end thereof. A vertical conveyor that interacts with the supply and discharge passages of the load to be transported is supported, and at each lower end a pickup and delivery device for the load to be transported is supported, and the load to be transported. It is composed of a gate-shaped side platform having a structure arm frame which can be vertically swung and pivoted with a product supply passage and a discharge passage.

State of the Art From German Patent 1290875, a loading and unloading device for ships, in particular for transporting packaged goods or raw materials for loading, is known.
In this known cargo handling apparatus, a free end is provided with a spiral conveyor constituted by an endless conveyor belt driven by a guide roller, carries a vertically supported mechanism, and an upper free end is undulating and rotatable. Above the spiral conveyor supported in the support structure, the feed belt is arranged in the transfer area on the transfer side of the conveyor supported in the body arm, and the feed belt is mounted in front of it on the bridge platform. And the second spiral conveyor is arranged rotatably about its longitudinal axis in a support frame inside the support structure, and on the outer wall of the support structure. Is formed in a spiral shape that is screwed with the outer shape of the mating member formed on the inner wall of the conveyor to form the outer shape of the spiral pitch of the conveyor. Furthermore, the upper conveyor has a transfer roller in front of the upper offset drum. Is mounted Is, the transfer roller is rotated being supported in the support frame of the conveyor in the conveying direction.

On the other hand, a cargo handling device is also known from DE 2622399, especially for ships loaded with packaged goods. In this known loading and unloading device, the proximal end is connected to a stationary supply and discharge belt for the load to be transported, the upper end of which is in a support frame supported on a fixed support structure. A vertical conveyor arranged and pivotable in this structure about a vertical axis and provided with a rotary table for transferring the goods to be conveyed from there onto or from the supply channel. There is a passage,
The turntable is provided with a central opening for a vertical conveyor passage to pass through the stripper, and within the delivery or supply area of the vertical conveyor passage of the support frame above the turntable, A belt conveyor is provided, and at the end facing away from the vertical conveyor path of the belt conveyor, there is provided a plate-shaped stripper capable of rotating around a vertical axis, and the belt conveyor is also provided. On both sides of the end facing away from the vertical conveyor path of the, there is provided a transfer path extending towards the rotary table and further in the area of a fixed supply or delivery bell for the goods to be transported. Is provided with another stripper that can rotate about a vertical axis above the turntable.

Both of the known cargo handling devices described above have a common movable platform having a horizontal bridge platform and a body arm frame, and are capable of vertically undulating on one side hingedly connected to the platform. And at its free end a vertical conveyor is supported such that the overall configuration is such that the vertical conveyor assumes a vertical position in each undulating rotational position of the body arm frame. The vertical conveyor is also adapted to interact with a supply and discharge belt for the goods to be transported, which belt is arranged on a vertically displaceable body arm frame. Thus, the cargo reaching it is either delivered to a vertical conveyor or, when the cargo is unloaded, from the vertical conveyor to a supply or discharge conveyor belt.

In this case, the supply and discharge conveyor belts arranged in the body arm frame and interacting with the vertical conveyor extend over the entire length of the body arm frame,
On the gantry side, another supply conveyor belt is assigned to a supply or delivery belt for supplying or delivering a load. If the structure arm frame having the supply or discharge conveyor belt above it is configured to be displaceable in the vertical direction on the gantry of the cargo handling device, the supply or discharge conveyor belt is assigned to this. Another conveyor belt is disposed across the gap between the supply conveyor belt and the conveyor belt, and the other conveyor belt is the conveying surface of the supply or discharge conveyor belt or the conveyance of the supply belt assigned to the supply or discharge conveyor belt. A supply or discharge assigned to it which is not arranged in the plane but faces the supply or discharge conveyor belt and is in the plane located in the lower plane, facing the supply belt and facing this conveyor belt. And in the rotating area of the discharge conveyor belt, the transfer rollers provide that the goods being conveyed are provided by the staggered arrangement of conveyor belts. Is provided so as to overcome the difference in height is.

However, in the cargo handling device having the above-mentioned configuration, it is suitable only for transporting large bags and packaged cargo, but in order to avoid movement of the cargo, the cargo pallet on which the cargo is loaded is always on a horizontal plane or a vertical plane. Since it can be transported only in the plane, it is not suitable for transporting a cargo pallet loaded with such cargo.

PROBLEM, SOLUTION, AND ADVANTAGE The present invention provides a loading pallet on a material handling device to provide a continuous transfer point at a position where the support frame is movable outwards with respect to a support frame movable inward and outward of the device. In the transport plane, the movable parts of the support frame are moved inward and outward so that the transport plane is simultaneously adapted to the length of the respectively obtained travel path, and during transport of the load pallet The technical problem is solved by ensuring that the cargo pallets are transported without moving the cargo on the pallets.

This problem is solved by the features of claim 1.

With the device configured as described above, cargo handling work using a loading pallet is possible.

Here, the loading pallet is equipped with a lifting platform, and is taken out of the cargo hold or supplied to the cargo hold by a vertical conveyor that vertically descends to the cargo hold of the ship, and the vertical conveyor is According to the present invention is delivered or loaded onto the supply or discharge conveyor belt of the body arm frame, all of these operations being determined by whether the operation is loading or unloading. Also, at the same time, after the load pallet has been delivered by the feed and discharge conveyor belt, the load pallet is fed on a flat conveying path towards another vertical conveyor on the wharf side, During the transport operation, the load pallet is never moved from the transport corridor in one plane before being transferred to the vertical conveyors located on the wharf side.

The transport passage is composed of three conveyor belts, and the first conveyor belt among them is
The second conveyor belt, which is involved in the inward and outward movement of the movable support frame on the side where the ship is located, is arranged and mounted in a fixed support frame fixed to the body arm frame. To be The space between the fixed support frame and the second conveyor belt, which is caused by the inward and outward movement of the movable support frame, is made movable between each of these first and second conveyor belts. , And bridged by a third conveyor belt having at least an equivalent size corresponding to the loading pallet, each said conveyor belt having a length and / or width corresponding to twice the reference area of the loading pallet, For example, each of the two combination pallets is fed to a movable conveyor belt, or the conveyor belts are all
For example, it is possible to increase the handling capacity of the material handling device if it has a width that can supply two juxtaposed loading pallets at the same time.

On the other hand, the traveling speed of the movable third conveyor belt between the first conveyor belt of the movable support frame and the second conveyor belt of the fixed support frame is from the first conveyor belt to the fixed support frame. The distance is determined by the moving length of the movable support frame from the fixed support frame on the body arm frame. In addition, the movable support frame having the first conveyor belt has a fixed support frame such that the gap between the first conveyor belt and the second conveyor belt of the fixed support frame is completely eliminated through the third conveyor belt. As they are moved in, each of these conveyor belts will have the same speed of rotation (movement). Then, in this case, the moving speed of each conveyor belt can be made relatively high, but in consideration of the centrifugal force generated when the loading pallet is forwarded, the load on the loading pallet should not be dropped. When the movable support frame having the first conveyor belt travels outward from the fixed support frame, the traveling speed of the movable first conveyor belt is relatively high. So as to match the length of the space between the second and third conveyor belts.

Therefore, an important advantage of the cargo handling apparatus according to the present invention is that it can transport not only a loaded pallet loaded with packaged luggage but also bagged luggage without any problem.
Moreover, since the traveling operation is performed only in the vertical and horizontal directions for the loading / unloading work of the loading pallet, the loading items on the loading pallet are not moved, and the loading items are transferred between the conveyor belts on the structure arm frame in the device. The point is that they are all made up continuously.

Other advantages of the invention are set forth in the dependent claims.

Only the longitudinal members 167, 168 of the above are shown so that they can be identified, and the carrying framework 160 can also optionally be provided with side covers for protecting the load.

The carrying frame 160 is held and guided in the load plate 150 and is movable in the up and down direction shown by the arrow X1. Therefore, the carrying frame 160 is indicated by reference numeral 500. It can move within the cargo hold of existing ships. Here, the entire length of the carrying frame 160 is such that, in a lowered state, the end thereof located near the base surface portion 160a or at the base surface portion 160a can stop at the loading surface or the inner surface of the ship bottom. The directional dimensions are substantially determined, and the carrying frame 16
Due to the vertical mobility at 0, it is possible to easily correspond to the loading surface in each cargo hold and the waterline position of the ship itself.

Thus, the vertical movement of the carrying frame 160 is the first
As indicated by reference numeral 161 in the figure, it is preferably carried out by electric drive means, but it is also possible to use drive means of different construction. In the case of this embodiment, the drive means 161 is preferably a drive motor,

The second conveyor belt 270 is disposed in the fixed support frame 40 and has a length shorter than that of the fixed support frame 40, that is, the second conveyor belt 270.
The length of the movable support frame 50 is larger than that of the fixed support frame 40 when it moves into the fixed support frame 40.
The dimensions are determined so as to be shorter by the area determined by the part. Therefore, the rear end portion 53 of the movable support frame 50 that can move in and out forms a space with the front surface of the second conveyor belt 20 in the fixed support frame 0 fixed to the support arm 130. It's over.

Further, the third conveyor belt 370 is arranged in the space between the first conveyor belt 170 and the second conveyor belt 270. This third conveyor belt 370
Has a size capable of accommodating only one loading pallet, that is, the length of the third conveyor belt 370 approximately corresponds to the length or width of the loading pallet, and the movable support frame 50 is Once inserted into the stop position within the fixed support frame 40, this third conveyor belt 370 is connected to the end of the first conveyor belt 170 and then the second conveyor belt 270 is connected to it. As a result, with respect to the transported object, a continuous transportation path located in one plane is configured.

On the other hand, when the movable support frame 50 is moved outward from the fixed support frame 40, a space larger than the length of the third conveyor belt 370 is provided between the two first and second conveyor belts 170 and 270. Occurs. And in this case,
In order to surely carry the transported object through this space, the third conveyor belt 370 has
It is movable between the first and second conveyor belts 170 and 270 in the direction of arrow X3. In addition, the third conveyor belt 37
0 itself is a set of curved rollers 371,372 at each end.
A drive means comprising an endless belt running therethrough and suitably configured to drive either one of the two curved rollers 371, 372 is designated by 375.

The upper traveling belt portion of the third conveyor belt 370 is indicated by reference numeral 370a, the lower traveling belt portion is indicated by reference numeral 370b, and the third conveyor belt 370 is
It is arranged on a sliding portion 378 that is movable in the direction of arrow X3 on a guide rail (not shown). Because of this mobility, a reversible drive means 376 is provided, so that the slide 378 with the third conveyor belt 370 can be moved both in one direction and in the other.

The second conveyor belt 270 disposed inside the fixed support frame 40 similarly includes the curved rollers 2 at both ends.
A suitable drive means for driving either one of these two curved rollers 271,272 is shown at 275 and comprises a second conveyor belt 270. The upper traveling belt portion is designated by the reference numeral 27a, and the lower traveling belt portion thereof is designated by the reference numeral 270b.

Furthermore, within the region on or near the base surface and in its end region facing the third conveyor belt 370, the movable support frame 50 is arranged so that the third conveyor belt reaches the region of the first conveyor belt 170. The belt 370 has an open structure for surely moving and traveling inward, and the overall arrangement of the first to third conveyor belts 170, 370, 270 is the same as those of the upper traveling belt portions 170a, 370a, 270a.
Are located in one plane to form a continuous passage. The inward and outward movement of the movable support frame 50 with respect to the fixed support frame 40 is indicated by the positions A1 and B1 in FIG. 1, and the vertical movement of the vertical conveyor 60 is the position A2, B2 and C
Shown in 2.

Thus, the first conveyor belt 17 that can move inward and outward together with the lifting table 162 and the carrying frame 160.
0 and the second conveyor belt 270 in the fixed support frame 40
And the respective movable means 164, 175, 275, 375, 376 for the movable third conveyor belt 370 are configured in the controller 80, and the transported object is the first conveyor belt facing away from the vertical conveyor 60. When you reach the end of 170,
The movable third conveyor belt 370 is
The conveyor belt 170 is moved to the delivery position.

Therefore, when the operation of each of these conveyor belts is started, the transported object is transferred from the first conveyor belt 170 to the third conveyor belt 370, and the movable third conveyor belt 370 moves. , The first and second
Of the first conveyor belt 170 to the third conveyor belt 370 and from the third conveyor belt 370 to the second conveyor belt 270. Direct transfer of the transported object is sequentially performed.

On the other hand, when the movable support frame 50 having the first conveyor belt 170 travels outward from the fixed support frame 40, the third conveyor belt 370 causes the objects to be conveyed from the first conveyor belt 170. After taking over, the vehicle travels to the loading area of the second conveyor belt 270.

Then, the transported object is transferred to the third conveyor belt 370.
Is moved from the third conveyor belt 370 to the second conveyor belt 270, and during this movement, the third conveyor belt 370 itself takes over the succeeded pulling conveyance. The rotation of the belt is discontinuous since no goods can be transported.

After that, when the third conveyor belt 370 is once moved to the position of the first conveyor belt 170 or the second conveyor belt 270, the belt of the third conveyor belt 370 is rotated and the first conveyor belt 370 is rotated. Belt 170 to the third
The article to be conveyed can be delivered to the conveyor belt 370, or the article can be unloaded from the third conveyor belt 370 to the second conveyor belt 270. 3, each conveyor belt 170,
The direction of rotation of 270 and 370 depends on whether the transported objects are loaded,
Or it is decided by whether it is unloaded.

Here, each of the first to third conveyor belts
The rotation speeds of the 170, 270, 370 are the same, but in particular, the moving speed or traveling speed of the third conveyor belt 370 is the length of the passing distance, that is, the first conveyor belt 170.
Is determined by the length of the space between the first conveyor belt 17 and the second conveyor belt 270.
When the distance between 0 and the second conveyor belt 270 is negligible, the movement of the third conveyor belt 370 does not need to be very fast, while those of the first conveyor belt 170. When there is a considerable distance between the second conveyor belt 270 and the third conveyor belt 270, it is preferable to move the third conveyor belt 370 by increasing the moving speed in order to achieve the cargo handling work with high efficiency. In terms of points, the traveling speed of the third conveyor belt 370 needs to be calculated so that there is no undesired movement of the load on the loading pallet. That is, the rotation speed and traveling speed of the third conveyor belt 370 are controlled by the controller 80 and the conveyor belts 170, 270,
The drive means of 370, ie, respectively, the function of passing through the movable third conveyor belt 370 and the lifting platform 162.
Since it is controlled as the traveling operation of the vertical conveyor, the loading / unloading device 165 for the transported object is used to lift the platform 162 of the vertical conveyor 60.
Also, continuous transportation is performed through the loading or unloading belt 70 for the transported object to the unloading or loading location located in the wharf zone.

Next, as shown in FIG. 1, in the present embodiment, a vertical support frame 260 is disposed at the rear end portion 130a of the support arm 130 of the structure arm frame 30, and the supporting frame 160 is provided. Is configured the same as. A lifting platform 262 having a carriage 263 is arranged on the vertical support frame 260, and the vertical movement of the lifting platform 262 in the direction of the arrow X4 is indicated by reference numeral 264, and is the same as the above case. The driving means connected to the control device 80.

That is, the vertical support frame 260 carries, at its base end, a load / unload device 265 for transported objects, which has the same structure as the load / unload device 165. Then, the lifting platform 2 on the vertical support frame 260
The traveling operation of 62 is synchronized with the operation sequence of the lifting platform 162 and the first or second conveyor belts 170, 270, 370, and the transported object to be unloaded via the loading or unloading device 265 is It is adapted to be conveyed to the area of the second conveyor belt 270 by means of a lifting platform 262, and from the second conveyor belt 270 the conveyed objects to be conveyed are subsequently transferred. It is once delivered to the third conveyor belt 370 moved to the position of the second conveyor belt 270. After that, the third conveyor belt 370 travels and moves with the delivered objects being loaded, and the first conveyor belt 17
While being brought into contact with 0, the object to be transported is transferred from there to be carried to the lifting platform 162 of the vertical conveyor 60.
Then, at the lifting platform 162, the first conveyor belt 1
Upon receipt of the load from 70, it travels to the loading or unloading device 165, where it is delivered into the cargo hold 500. In other words, loading a ship
In this way, it is possible to perform within the minimum unit time. Further, unloading is performed in the same manner, but in this case, the first to third conveyor belts 17 are used.

Then, in the state of being moved inward, each two transport passages 166 are positioned in the carrying frame 160 and occupy a space corresponding to the area of the transport platform 163 in the lifting platform 162 (FIG. 3). Due to the inward and outward movement of the transport passages 166, the transport passages 166 are moved into the carrying framework 160 so that the vertical conveyor 60 has a minimum cross-sectional dimension and the dimensions are palletized. Because of the approximate surface area, the vertical conveyor 60 can be moved inwardly within the free space of several side-by-side pallet loads resulting from the removal of the load from the pallet.

Further, pallet lifting means 430 is arranged in the area of the second conveyor belt 270 (FIG. 5),
By this means, it is possible to raise and lower the loading pallet loaded with the objects to reach the second conveyor belt 270. This lifting means 430 serves to set a space above the second conveyor belt 270, and a terminal pallet 445 is inserted in this space to load the load pallets into these terminal pallets.
Be able to put it on 445. Each of the loading pallets has a different shape and may be damaged, and a complete pallet stand cannot be obtained. Therefore, the loading pallet has a plate-like shape and is low in height, and can be gripped by a fork of a forklift truck. A so-called terminal pallet that can be moved up and down is used. Such terminal pallet-loaded pallets are completely stacked and assembled, and even if the pallet carrying the loads is damaged, the pallets can be kept stacked.

The pallet lifting means 430 comprises a fork corresponding to a fork of a forklift truck and a hydraulic lifting device, which is movable under a loading pallet reaching a conveyor belt, but has a different structure. It is also possible to apply Preferably, the lifting device 430 is arranged at the end of the second conveyor belt 270, ie the end facing the support frame 260 with the lifting platform 262. Then, the terminal pallet is removed by a magazine or a supply shaft (not shown) by each selection device. After removing the terminal pallet, the entire stack of terminal pallets on the supply shaft is moved upwards. The terminal pallets are also removed by, for example, a hydraulically driven lateral slider, and unnecessary terminal pallets are returned to the supply shaft (Fig. 5).
